Have been browsing the posts about bio-diesel. After all the equipment for the truck (if your not going to invest in the manafacturing side), Bio being sold at a higher cost at the pump than #2. It is way more expensive to run bio. Why should I use it? Seems to me there are people out there that are promoting this stuff as the next best thing to sliced bread (and oh by the way, they'll sell you home depot gathered items as a complete system for $$$$$$$$$). And no I don not have the time to do it myself. So i think i'll stick (slave) to the big oil companies. Supply and demand...................mmmmmmmmm.
